APPARATUS FOR PRODUCING COPIES OF WRITIN'GS.

SPECIFICATION forming partV of Letters Patent No.` 242,919, dated June 14, 1881.

Application tiled January 31, 1881. (No model.) Patented in England July 3, 1880.

i in Means and Apparatus Employed in Producing Copies of Writings, Drawings, and other Delineations, (for which I have received Letters Patent in England, No. 2,725, dated 3d July, 1880,) of which the followiagis a specification.

The invention has for its object improvements in means and apparatus employed iu producing copies ot' writings, drawings, and other "delineations, and it relates to that class of apparatus in which a paper stencil is produced-by grooves at the ends to receive rods or bars, to

enable the paper stencil to be stretched over the frame to produce the copies.

In order thatm y said invention may be more clearly understood and readily carried into effect, I will proceed, aided by the accompanying drawings, more fully to describe the same.

In the drawings, Figures l and 2 are plans of two opposite sides. Fig. 3 is a view of the front edge. Fig. 4t is a view of one of the side edges. Fig. 5 is a longitudinal section, and Fig. 6 is a cross-section, ot' my improved apparatus. Fig. 7 is a plan of the inking-plate separately, and Fig. 8 is an enlarged section of a portion of the frame and of my new wire,

The straining rods or bars d are capable of being readily locked in position and unlocked by means of hooks h. Other means may, however, be employed for this purpose.

The surface a is, according to my invention, formed ot' a number of line wires laid closely side by side, and the method I prefer to employ in carrying this part of my invention into el'ect is as follows: I first obtain a cylinder of `suitable diameter, and formed with a longitudinal groove or recess along its surface from end to end thereof. I then wind the wire around the same, taking care to lay each coil quite close to its neighboring coils. When the cylinder is covered to the extent required I coat the wire with a cement, which I leave on a sufficient time to insure the wire adhering thereto, but which is of such a character as to remain pliable sufficient-ly long to enable the wire to be cut by running a pair of shears or other suitable cutter along the groove or recess in the cylinder, and then to be removed from the cylinder and cemented onto Iany suitable surface. l

Having thus described the nature of my said invention and the Inode in which I carry the same into effect, I would have it understood that what I claim is 1. The Inode of producing surfaces for stenciling apparatus herein described, which consists in taking a cylinder of suitable diameter and formed with a longitudinal groove, winding wirearouud the same, coating the wire with cement, cutting the wire in line with the groove, removing the wire, and then mounting it on a suitable backing, as set forth.

2. A stenciling apparatus having a closelylaid surface of wire secured to a suitable backing.

3. In a stenciling apparatus, the frame having a wire surface on one side, a straining and printing bed on the other, and a space in the center adapted to receive the ink-plate, as set forth.

4. A stenciling apparatus consisting of a frame formed with a central space, c, having grooves g, for an inkplate,f, a wire surface, a, cemented thereto, a printing-surface, b, and straining-rods d, as set forth.
